Description
Kofloc 8500MM Mass Flow Controller/Mass Flow Meter with Indicator
Kofloc 8500MM Mass Flow Controller/Mass Flow Meter with Indicator is an advanced, compact digital mass flow controller engineered for precise gas measurement and automated flow control in analytical, semiconductor, and industrial process systems. Featuring an integrated local display indicator and micro-solenoid valve control, the Kofloc 8500MM Mass Flow Controller delivers high-accuracy thermal mass sensing without requiring temperature or pressure corrections. Housed in a compact panel-mount or stand-alone chassis with multi-gas functionality, local setting keys, and RS-485 Modbus communications, it provides reliable gas control for laboratories and production lines.
Technical Overview & Operation
Kofloc 8500MM Mass Flow Controller/Mass Flow Meter with Indicator operates using a high-precision thermal mass sensor paired with a fast-acting proportional solenoid control valve. Gas passing through the laminar flow element transfers heat to a capillary sensor tube. Internal bridge circuitry measures this thermodynamic heat shift to calculate true mass flow independent of line pressure or temperature shifts.
The integrated digital indicator presents real-time flow rate, accumulated volume, and setpoint parameters directly on the front screen. Operators can adjust flow setpoints locally via tactile control keys or command the unit remotely using analog 0–5V/4–20mA signals or RS-485 digital communications. Multi-gas software curves allow users to switch between standard gases ($N_2$, Air, $Ar$, $CO_2$, $O_2$) without returning the unit for factory recalibration.
